Both. Huge businessmen and corrupt officials steal for their personal gratifications which is driven by their own greed. On the other hand, poor people tend to steal in order to survive. Scarcity of basic necessities is the usual reason behind this, it pushes them into their limits to commit stealing even though they knew from the very beginning that it was not a good thing. They are like facing a "no choice" situation so I can't blame them.
If you will ask me if they're the same, I say YES. It doesn't matter whether you only stole a piece of apple or millions of money, stealing is stealing it was a sin. However, I believe that sometimes in life the end justifies the means so I'll be more compassionate for the poor ones if proven guilty
